If drano causes an explosion, either you or your beneficiary will be rich. Too bad I've used it many times and I am not rich yet! I use the crystal Drano, it works much better for me than the liquid kind. You'll be surprised. Everyone loses hair. Drano is supposed to work on hair, grease clog, soap scum and it works for me.
Maybe try not throwing a match in the drain after pouring in the Drano. Other than that, Drano is fine. Is that the redneck version of Drano?
A plunger should do the job. What I'd be concerned about is whether the hair did not just get pushed further down the line and got stuck there.
